2. Spatial variability of crop and soil properties in a crop-livestock integrated system.
The knowledge of spatial variability soil properties is useful in the rational use of inputs, as in the site specific application of lime and fertilizer. The objective of this work was to map and evaluate the spatial variability of the corn and pasture, soil chemical and physical properties in crop-livestock integrated system. The study was conducted in an a

3. AGRICULTURE OF PRECISION: MANAGEMENT OF THE FERTILITY WITH APPLICATION OF THE VARIED RATE OF FERTILIZERS AND ITS RELATION WITH CROP YIELDS / AGRICULTURA DE PRECISÃO: MANEJO DA FERTILIDADE COM APLICAÇÃO A TAXA VARIADA DE FERTILIZANTES E SUA RELAÇÃO COM A PRODUTIVIDADE DE CULTURAS
The agriculture of precision has been an important tool for the characterization of the spatial variability of soil attributes and crops. Thus, there is many options to elaborate thematic digital maps that can improve the soil and crop management. In this work, two croplands that has been managed with precision agriculture during several years were selected.

6. Classificação fitofisionômica do cerrado no Parque Nacional da Chapada dos Veadeiros, GO, com a aplicação de uma análise combinatória com filtros adaptativos em imagens TM Landsat
The soil fertility and water availability are some of the many factors which controls the Cerrado biome vegetation and are in charge of a great diversity of phytophysiognomies that encompass fields, savanna or forest formations. The vegetal mass amount variation occurs according to the vegetation formations and takes its effects over the spectral signatures

8. Estimativa da área e do tempo de permanência da vegetação secundária na amazônia legal por meio de imagens LANDSAT/TM
- Secondary vegetation, formed by natural regeneration of areas that are deforested and later abandoned, have many functions relevant to the ecology of the landscape in which it is embedded such as fixation of atmospheric carbon, maintenance of the biodiversity and the connection among forest remnants and restoration of soil fertility. The latter function is

11. APPLICATION OF PRECISION AGRICULTURE TECHNIQUES IN SMALL FARMERS / APLICAÇÃO DE TÉCNICAS DE AGRICULTURA DE PRECISÃO EM PEQUENAS PROPRIEDADES
The adoption of precision agriculture techniques finds great limitation because of the high cost, not always guaranteeing the expected economic return. Among the consequence of this elevated cost it is the restriction use of this technology in small farmers, characterized by the family farm. The present work approaches a bibliographical study about the situa
